Highlights

The actors get the script a few days before filming, and know little about the larger arc or mysteries.

The producers confirm (again) that they have an arc for the whole show.

Before each season, the writers sit together for 3 weeks and plan the arc for the whole season.

There is always room for improvisation, especially how the characters develop relate to each other. For instance, Michael and Jin were meant to be enemies, but the chemistry between the actors led to their emerging friendship.

They have to stick to the mythology of the Island (like DHARMA) and hope they don't "f*** up".

The fan response does have an influence on the show.

The complaints about the re-runs prompted ABC to change the schedule for season 3

The producers were disappointed because they were not nominated for an Emmy Award for best drama.

Damon: "It’s interesting that you should ask about time because... you’re making a basic assumption that they’ve been there as long as they think they’ve been there. I would say by the end of Season 3, that very different idea..." Carlton: "Stop right there, Damon, stop right there."

The panel host commented, "Damon, the actors looked surprised when you said that!"

They are asked about an underwater hatch, and they decline to confirm or deny the existence of an underwater hatch.
